PACKAGE-WRAPPING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 643,622, datedFebruary 20, 1900.

Application filed January 5, 1898. Renewed Tune 28, 1899. Serial No.722,187. (No model.)

To ttZZ whom it may concern:

Be it known that I, RICHARD A. BERGER, a citizen of the United States,residing at New York, (Brooklyn,) in the county of Kings and State ofNew York, have invented certain new and useful Improvements inPackage-Wrapping Machines, of which the following is a full, clear, andexact specification.

This invention relates to that class of machines which are designed toapply wrappingmaterial to articles of merchandise, particularly thattype wherein each wrapper or wrapper-section is folded longitudinallyupon the article and has its ends down folded, then laterally folded ortucked in, and, finally, lapfolded over the downfolded and laterally.-folded or tucked-in parts to completely inclose the article and protectit from the effect of atmospheric influences.

The present invention is intended specially for applying wrappingmaterial to blocks of chewing-gum, each block comprising fivesuperimposed layers, more or less but I wish it clearly understood thatthe invention is capable of being practicably and successfully used forapplying Wrapping material to various articles of merchandisesuch assoap cakes,chocolate,and the like-in such manner that the articles arecompletely inclosed by folding the wrapping material longitudinallyaround the same, downfolding portions of the ends, laterally folding ortucking in parts of the ends, and lapfolding the other parts of the endsupon the lateral folds or tucks.

The chief object of my present invention is to provide novel meanswhereby the article to be inclosed within a wrapper is under perfectcontrol of parts of the machine and cannot be displaced or shiftedrelatively to the wrapper from the time it is placed in proper relationto the latter and is completely inclosed thereby.

The invention also has for its object to provide a package-wrappingmachine with wrapping material in the form of webs wound on reels andwith novel means for drawing the webs longitudinally the proper distanceat regular intervals to place the wrapping material over the articleswhich are to be inclosed within wrappers severed from the webs atregular intervals.

The invention also has for its object to provide a package-wrappingmachine wherein the wrapping material proper is in the form of a webwound upon a reel, and the binder is also in the form of a web woundupon a reel, and means are provided for severing a wrapper-section fromthe webs and subsequently shifting the binder of the Wrappersection intocorrect position, so that the wrapper-section proper will be of agreater length than the binder to enable the ends of the Wrapper-sectionto be properly folded and the binder to be applied around the article tobind the whole in position.

The invention also has for its object to provide a package-wrappingmachine with new and improved folding devices for folding thelongitudinal edges of the wrapper-section one upon the other, turningdown portions of the ends of the wrapper, tucking in parts against suchturned-down portions, and subsequently lapfolding portions upon thetucked-in parts.

The invention also has for its object to provide a package-wrappingmachine with wrapping material in the form of a plurality of webs, oneof which constitutes a binder-web and is provided with adhesive alongone edge and novel mechanisinfor moistening the adhesive edge of thebinder-web, so that when the article is subjected to the action of thefolding mechanism the moistened adhesive edge is secured and a perfectpackage is produced.

The invention also has for its object to provide a new and improveddevice which serves to secure the adhesive part of the wrappingmaterial, to partially fold the ends of the latter, to remove thecompleted package from the folding box or chamber, and to place it in aposition from whence it may be carried or conveyed to any pointdesired.

The invention also has for its object to provide a new and improved armwhich is provided with wings that serve first to form parts of the foldsat the ends of the packageand to subsequently lift the completed packagefrom the folding box or chamber and deliver it at a point from whence itmay be carried or conveyed to the place desired.

The invention also has for its object to provide new and improved feedmechanism for ICO advancing the webs of wrapping material to place theleading edges thereof in position to be seized by nipping mechanism bywhich the webs are drawn longitudinally in proper relation to thearticles which are to be inclosed within wrappers.

The invention also has for its object to provide a brake mechanismautomatically operated at proper intervals to arrest the momentum of thereel on which the web of tin-foil is wound, whereby an undue quantity ofthis web will not be unwound, due to the momentum of the reel, at thetime that there is a pause in the longitudinal movement of the web and awrapper-section is being severed.

The invention also has for its object to generally improvepackage-wrapping machines and to provide a machine of this characterwhich will practicably and successfully apply wrappers to articles ofmerchandise and fold in the ends in such manner as to entirely inclosethe articles.

To accomplish these objects, my invention involves the features ofconstruction, the combinations or arrangements of parts, and theprinciples of operation hereinafter described and claimed, referencebeing made to the accompanying drawings, in which Figure 1 is a top planview of my improved package-wrapping machine, omitting the reel whichcarries the tin-foil and waxed paper.

Fig. 21 is a detail perspective view ofthe two horizontally-moving slides which carry the nipper-jaws. Fig. 22is a sectional plan view to show the manner in which the yoke-frames ofthe gripping and transferring jaws are mounted. Figs. 23 to 28,inclusive, are detail views of vibratory lever-arms and cams for movingthe same to actuate parts of the machine, as will fully hereinafterappear. Figs. 29 to 35, inclusive, are views showing the manner in whichthe wrapper composed of tin-foil,waxed paper, and a binder is folded toentirely inclose the article of merchandise.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail; but inasmuch as Ibelieve that the operation of the various parts of the machine will bemore rcadilyunderstood by first describing the manner in which the foldsof a wrapper are disposed with relation'to the entire package, I willfirst describe the folds without reference to the mechanism wherebythese folds are produced. For this purpose reference is first made toFigs. 29 to 35, inclusive. In Fig. 29 a wrapper is represented as laidupon the upper side of an article, such as a block of chewing-gum,

the article or chewing-gum being indicated by dotted lines. The wrapperis composed of three layers, first, a layer 1 of thin waxed paper;seconda layer 2 of tin-foil,and,third, a binder 3, which in practicewill bear the name of the firm putting up the article or chew: in g-gumand any other advertising matter that may be desired. The layers ofwaxed paper and tin-foil are coequal in dimensions; but the binder isconsiderably shorter than the wrapper proper, composed of the layers 1and 2. At one side'edge, as at 4, the binder projects beyondo'ne'longitudinal side edge of the waxed paper and tin-foil, and thisprojecting portion is provided on its under side with adhesive material.During the wrapping of the package this adhesive margin or projectingedge after being properly moistened is cemented down upon the oppositelongitudinal edge portion of the binder for effectually securing thepackage. The parts being arranged as shown in Fig. 29, they are reversedin position-that is to say, they are turned upside downso that thearticle of merchandise or the block of chewing-gum is uppermost or liesabove the wrapper, this taking place in the folding-box of the machine,as will hereinafter appear. As the wrapper and article are pushed intothe folding-box the longitudinal edge portions of the wrapper are forcedupward into a perpendicular position, as shown in Fig. 30. One side ofthe wrap per is then pressed downward upon the article, as at 5, Fig.31, and subsequently the other side is folded down, as at 6, Fig. 32,and the adhesive margin 4 is pressed down, so as to cement theoverlapping parts of the binder. After this has been effected endportions of the waxed paper and tin-foil are folded downward, as at 7,Fig. 33, then the triangular portions 8, Fig. 33, are folded or tuckedin laterally, as shown at 9, Fig. 34, and subsequently the remainingprojecting end portions 10, Fig. 34, are folded upwardly against thelaterally-folded or tucked-in parts 9 and the downward-folded portions 7to produce the complete package, Fig. 35, wherein the article orchewing-gum is effectually inclosed and protected from the effect ofatmospheric influences. Inasmuch as the waxed paper is comparativelythin and the tin-foil lies outside of the same the upward folds 10 willtend to maintain their folded position; but it is possible under certaincircumstances to tuck these end portions 10 under the binder, althoughthis is not considered essential, and therefore is not shown and willnot hereinafter be referred to.

It will be observed that in the completed package the binder'is onlyequal to the length of the article inclosed in the wrapper, and it isfor this reason that the binder, as shown in Fig. 29, is of a lengthconsiderably less than the length of the layers of waxed paper andtin-foil, which, in fact, constitute the wrapper proper.

Having described the method of folding the tions, the wrappers and thearticles are transferred to the folding mechanism, the folds areperfectly formed to produce the wrapped packages by mechanical meanswithout hand manipulation, and the packages are lifted from the foldingbox or chamber and placed upon a suitable receiver or table, from whencethey may be removed.

The articles of merchandise (indicated by the numerals 12, Figs. 3 and6) which are to be inclosed within wrappers are stored in a verticalcolumn or stack in a magazine composed of two perpendicular standards13, (best seen in Figs. 1, 3, and 6,) constructed with channels, inwhich the ends of the articles lie and by which they are retained in acolumn or stack and are guided in a downward direction. The channeledstandards may be of any desired height to receive and 17, theconstruction being such that when the Y slide-plate is moved rearwardand the arms 16 lie directly under the lower open ends of the channeledmagazine-standards a single articleas, for instance, a block ofchewinggum-will fall by gravity upon said arms and lie between the frontedge of the slide-plate and the upturned flanges 17 of the arms 16,while if the slide-plate be advanced or moved forward the articlecarried by the arms 16 will also be carried forward, and the solidportion of the slide-plate will move under the column or stack ofarticles and support the same until the article carried by the arms 16is removed therefrom and the slide-plate is again moved rearward toplace the arms directly under the lower open ends of themagazinestandards, whereupon the operation before described will berepeated. The slide-plate moves back and forth directly above a table18, Figs. 1 and 6, and at the right-hand side of this table is anothertable, as at 19, Figs. 2, 4, and 18, over which the wrapping material ismoved longitudinally. In wrapping acka es of chewin um the wra in ma- Db b p b terial is composed of webs, one of which is a simple paperbinder, while the other is composed of waxed paper lying above tin-foil.It is desirable that the tin-foil and waxed paper be compelled to movelongitudinallyin unison, and for this purpose I unite the waxed paperand the tin-foil by heat and pressure and then wind this compound webupon a reel 20. The paper-binder web is wound upon a reel 21. It ispossible, however, to wind the tin-foil and the waxed paper uponseparate reels; but where the waxed paper and tin-foil are united byheat and pressure and the compound web is wound upon a reel the tin-foilis strengthened to prevent tearing when pulled longitudinally, the waxedpaper and foil must move in unison, and their displacement relatively toone another is effectually prevented, whereby these parts of thewrapping material are susceptible of being practicably manipulated inthe machine in a better manner than if the waxed paper and foil werewound upon separate reels and simply superimposed without being actuallyconnected or united by heat and pressure. The binder-web is of a widthgreater than the width of the web of waxed paper and foil, so that onelongitudinal edge of the binder-web will project laterally past one edgeof the web of waxed paper and foil. This projecting edge is provided onits under side with adhesive, and therefore in each completed wrapperproduced, as will hereinafter appear, one side or edge portion of thebinder 3, Fig. 29, will project and be supplied with adhesive, asdescribed with reference to the part 4:, Figs. 29 to 35, the purpose ofthis being to cement or secure the package during the folding operation.Ata point near the magazine and above the inner end of the table 19,which lies under the webs, are located two plates 22 and 23, havingnotched leading edges, one plate being arranged directly above the otherand slightly separated therefrom. The compound web of waxed paper andfoil running from the reel 20 passes under the lowermost plate 23, whilethe binder-web running from the reel 21 passes between the two plates 22and 23, whereby the leading edges of the webs are slightly separated toenable the pairs of nippers, hereinafter explained, to seize and pullthe webs, one pair of nippers seizing the leading end of the compoundweb of waxed paper and tin-foil and the other pair of nippers seizingthe leading end of the binder-web. The compound web passes betweenelastic feedrollers 24, 25, and 25, Fig. 2, geared together at theirrear ends, as seen in Fig. 18, and designed to facilitate drawing acertain quantity of the compound web of waxed paper and foil from thereel 20 whenever the feedrollers are rotated. The elastic feed-rollers24 are mounted in a yoke-frame 24:, pivoted at its inner end portion, asat 24 to fixed parts of the machine-frame, so that if the outer end ofthe yoke-frame be raised the elastic feed-roller 24 will be elevatedfrom contact with the feed-roller 25 for the purpose of introducing thewebs of tin-foil and waxed paper, or, in other words, to facilitatethreading the machine with these webs. The binder-web passes between anelastic feedroller 25 and one of the rollers 24 and when rotated servesin a measure to advance the binder-web longitudinally toward thenippers. These feed-rollers are simply for the purpose of drawing aquantity of the webs from the reels and to facilitate the longitudinaldrawing or pulling of the webs by the nippers above mentioned, theconstruction and operation of which will hereinafter be fully describedin detail.

The feed-rollers 25 and 25 are rotated at regular intervals to drawwrapping material from the reels by any suitable means; but I.

have illustrated and will hereinafter describe, in connection with theactuating and driving devices of the machine, the particularrackand-pinion mechanism represented for rotating the feed-rollers.

It is proper to here state that when the tinfoil and waxed paper areunited by heat and pressure to form a compound web, as hereinbeforestated, it is not essential to provide feed-rollers for drawing thetin-foil and waxed paper from the reel which carries the same, becausethe compound web possesses suflicient strength to enable thereciprocating nippers to pull the web directly from the reel, and thesame remarks apply to the binderweb, in that this is ordinarily composedof paper which is comparatively strong. Therefore, while I have shownand described the feed-rollers and will hereinafter describe the meansby which they are positively rotated at regular intervals, I do notlimit myself to the use of these feed-rollers and their drivingmechanism.

A cutter for severing a web into wrappersections is located directly atthe left-hand side of the web flattening and guiding plates 22 and23-that is to say, the cutteris located at a point between theflattening and guiding plates and the magazine. The cutter is composedof two pivoted shear-blades 26 and 27, Figs. 4 and 17, operated atintervals, as hereinafter explained, so that when the leading ends ofthe webs have been drawn longitudinally in front of the magazine adistance sufficient to provide the material necessary for a wrapper theshear-blades constituting the cutter instantly close and smoothly severthe webs. As the webs are drawn longitudinally into a position in frontof the magazine the slide-plate 15 at the lower end of the magazine ismoved forward and an article lying on the arms 16 between the front edgeof the slide-plate and the upturned flanges 17 will be carried forwardand placed beneath the wrapper-section, so that the wrapper actuallylies above the article, and the article and wrapper-section are inproper relation to be subsequently carried to the folding box or chamber28, Figs. 1 and (5, through the medium of two gripping-jaws 29 and 30,(best seen in Figs. 6 an 22,) forming, respectively, fixed parts ofyoke-frames 31 and 32. The

yoke-frame of the gripping-jaw 30 is sleeved or loosely mounted upon ashort longitudinal shaft 33, arranged in suitable bearings in parallelplates 34, running from front to rear of the machine at or about thecenter thereof, one portion of this yoke-frame 32 being rigid with apinion 35. The pinion 35, loosely mounted on one end portion of theshaft 33, forms a fixed part of the yoke-frame 32, loosely sleeved onthe shaft at opposite extremities of the sleeve 36, which is fast to theshaft, as best seen in Fig. 22. The yokeframe 31 of the jaw 29 formspart of the sleeve 36, fastened to the shaft 33, which latter isprovided at one end, at a point outside of theleft-hand side plate 34,with an attached pinion 37. The pinion 35 of the yoke-frame 32 engages asegmental rack 38 at the inner side of the right-hand side plate34,while the pinion 37, which is secured to the shaft 33, on which thesleeve 36 is mounted, engages a segmental rack 39 at the outer side ofthe left-hand plate 34. The segmental racks are independently operated,as will be hereinafter explained, and they swing back and forth in adirection from front to rear of the machine. In what may be called thenormal position of the gripping-jaws 29 and 30 (indicated by full linesin Fig. 6) the jaw 29 lies substantially flush with the inner end of thetable 18, which is under the magazine, and therefore, when an article isdischarged from the magazine, as the wrapping material is drawnlongitudinally into a position in front of the magazine the article ispushed under the wrapping material and is placed directly over thegripping-jaw 29. During this time the grippingjaw 30, which is a part ofthe yoke-frame 32, lies in the folding-box, and after the wrappersectionand the article are in correct position above the jaw 29 the yoke-frame32 is swung in the arc of a circle and its jaw 30 leaves the folding-boxand cooperates with the jaw 29 to firmly grip and hold the article andthe wrapper-section, after which the two jaws gripping the article andthe wrapper-section swing forward in unison in the arc of a circle, andthe jaw 30 enters the folding-box 28, so

that the article and the wrapper are reversed.

in their positions, and the article will lie above the 'wrappersectioninstead of under the same, as when it was first gripped by the two aws.pendent of the jaw 30 to the position shown in full lines, Fig. 6.

The front wall 40, Fig. 6, of the folding-box is fixed or immovable,while the rear wall is composed of a clamp-jaw 41, Figs. 6, 7, S, and11, having a tailpiece 42 lying at the bottom of the box in such mannerthat when the article and the wrapper are deposited in the folding-boxby the transferring and gripping jaws above referred to pressure isapplied by the jaw 30 upon the tailpiece 42, the longitudinal sides ofthe wrapper are turned upward, and the clam p-jaw is caused to firmlygrip the opposite longitudinal sides of the article to press the wrappertightly against the side edges of the article and to firmly hold thearticle and the wrapper in fixed relation in the folding-box. By themeans de- The jaw 29 will then move back indescribed the article and thewrapper are under perfect control of mechanical parts of the machine andare absolutely prevented from displacement relatively to each other fromthe time they are seized by the gripping and transferring jaws andtransferred to the folding-box until the entire folding operation iscompleted. The complete folding of the wrapper by mechanical means willbe described later on.

The plate forming the gripping-jaw 30, or the yoke-frame of this jaw, isconstructed with an opening or recess to receive the clamp-jaw 41 whenthe gripping-jaw is lowered into the folding-box, as best seen in Fig.l, and the plate forming the gripping-jaw 29 is of such length that whenthe magazine slideplate 15 is advanced its arms 16, with their upturnedflanges 17, pass at oppositeends of the jaw 29, so that when the twogripping-jaws are closed together and are swung forward they raise thearticle from the arms and transfer the same, with the wrapper, to thefoldingpoint.

I will now proceed to describe the nipper mechanism by which the webs ofwrapping material are drawn or pulled longitudinally .into a position infront of the magazine and over the article to be wrapped. There are twopairs of nippers, composed of fixed jaws 43 and movable jaws 44 and 44.(Best seen in Fig. 21.) The fixed jaws-are carried by the inner ends ofhorizontally-movable slides 45, and to the inner end portion of oneslide the nipper-jaw 44 is pivoted, as at 46, and is articulated at oneside of its pivot to one extremity of a lever 47. The movable jaw 44 ofthe other nippers may form a rigidpart of a lever47, pivoted as at 46The reason for the difierences in the construction of the twonipper-jaws is that the nipper-jaw 44 closes upwardly against a fixedjaw, while the nipper-j aw 44 closes downwardly against a fixed jaw. Theouter ends of the levers 47 and 47 are provided with roller-studs, as at48, adapted to travel in longitudinal guideways 49 in the opposite sidesof a bar 50, which is pivoted at its outer end, as 51, to a fixed part52 of the machine-frame. The slides 45 are dovetailed to opposite sidesof a fixed plate 53, forming an extension of the machine-frame, andthese slides are pivotally connected by links, as at 54, with the upperends of vibrating levers 55, which at their lower ends are mounted on afixed stud 56 in such manner that when the levers are vibrated theslides 45 are reciprocated, and consequently the nipperjaws arecorrespondingly reciprocated. The bar 50 is adapted to be raised andlowered by a vertical rod 57, connected therewith at its upper end, asat 58, Fig. 2, so that if the bar 50 be raised by elevating the rod 57the levers 47 and 47 will be so actuated as to close the pivotedRipper-jaws 44 and 44 for the purpose of gripping the leading edges ofthe webs of wrapping material, and, conversely, if the bar 50 be loweredthe levers 47 .and 47 will cause the pivoted nipper-jaws to open andrelease the leading ends of the webs. The cams and connections foroperating the vibrating levers 55 and the vertical rod 57 at timedintervals will be hereinafter explained in the description pertaining tothe cam-shafts and driving devices of the machine, for which reason itis unnecessary to here explain the same.

In Fig. 2 the leading ends of the webs of wrapping material areindicated by the numerals 59 and 60, the web 59 being the binderweb andthe web 60 the compound web of waxed paper and'tin-foil. When the slides45 are advanced, the bar 50 is depressed and the nippers are opened toseize and grip the leading ends of the webs, one pair of nippers beingarranged to seize the binder-web 59 and the other pair to seize thecompound web 60. Vhen the nippers are in position to grip the ends ofthe webs, the bar 50 is raised and the pivoted nipper-jaws 44 and 44 areclosed against the fixed jaws 43, after which the slides 45, by theirconnection with the vibrating levers 55, are retracted or commence tomove outwardly, thereby drawing or pulling the webs between the webflattening and guiding plates 22 and 23 into a position in front of themagazine and over the gripping-jaw 29, Fig. 6, which at this time isflush with the table 18. As the webs are drawn longitudinally in frontof the magazine an article is discharged therefrom and placed over thejaw 29 under the wrapping material, as before explained. \Vhen therequisite quantity of wrapping material has been drawn by the nippersinto a position in front of the magazine, there is a pause in thelongitudinal motion of the nippers, and at this instant the shearblades26 and 27 close and sever the webs to produce a wrapper. Immediatelythereafter the nippers again move a limited extent in an outwarddirection to adjust the waxed paper and tin-foil into correct position,and then there is a pause in the motion of the pair of nippers whichseizes the waxed paper and tinfoil, while the other pair of nippers,which seizes the binder part of the wrapper, continue their outwardmotion and adjust the binder into such position that the waxed-paper andtin-foil parts of the wrapper will project from opposite ends thereof,or, in other words, the binder will be shifted and placed in theposition represented in Fig. 29, so that the end portions of the waxedpaper and foil can be folded by the folding mechanism, hereinafterexplained, without folding the end portions of the binder. hen the twopairs of nippers seize the leading ends of the webs of wrapping materialand commence their outward strokes, that pair of nippers which seizesthe waxed paper and foil move slightly faster at the beginning than thepair of nippers which seizes the binder, so that the Web of waxed paperand foil is drawn considerably ahead of the-binder for the purpose ofobtaining a wrapper in which the waxed paper and foil are of a greaterlength than the binder. In other words, as the nippers recede and pullthe webs longitudinally the nippers which grip the waxed paper andtinfoil move ahead or slightly faster than the n'ippers which grip thebinder-web until the requisite quantity of wrapping material is drawnlongitudinally, whereupon there is a pause in the longitudinal motion ofboth pairs of nippers and the quick-acting shear-blades sever the webs,after which the two pairs of nippers continue their receding motion; butthe pair of nippers which grip the binder-web moves ahead or slightlyfaster than the nippers which grip the waxed paper and foil, whereby thebinder is shifted 011 the waxed paper and foil and placed in suchposition relatively thereto that the waxed paper and foil extend fromopposite ends of the binder to provide the material necessary to befolded in at the ends of the article, while the binder itself is notfolded in at the ends, but is exactly or approximately the length of thecompleted package. When the wrapper is severed from the webs by theshear-blades, the edges of the binder and the waxed paper and foil atthe point where out are exactly coincident, and therefore it isnecessary to adjust the bindersection longitudinally to place the samein correct position so that the waxed paper and foil will project beyondthe binder at the ends of the wrapper. This is accomplished by thecontinued motion of the pair of nippers which grip the binder after theother pair of nippers, which grip the waxed paper and foil, haveadjusted the latter and cease their longitudinal motion. This will bebest understood by reference to Figs. 2 and 2 In Fig. 2 the shear-blades26 and 27 have just severed the webs to produce a wrapper. It will beseen that one pair of nippers has drawn the waxed-paper and foil webslightly beyond the binder. Thetwo pairs of nippers then shift thewrapper centrally over the gripping-jaw 29, Fig. 2", which is the jawover which the article is placed by the dischargingslide at the bottomof the magazine.

In Fig. 2 the article is represented as lying on the jaw 29, the wrapperis located above the article, one pair of nippers has placed the waxedpaper and foil in correct position relatively to the article, the otherpair of nippers has adjusted or shifted the binder part of the wrappercentrally over the waxed paper and foil, the shear-blades are open, andthe gripping-jaw 30 is approaching the jaw 29 for the purpose ofgripping the wrapper and the article between the two jaws andtransferring them to the folding-box.

As before stated, the binder-web is wider than the compound web of waxedpaper and foil to provide a projecting margin at one side, which isprovided with adhesive to cement or secure the wrapped package. Thisadhesive margin requires to be moistened, so that it can be subsequentlypressed down and secured. The moistening of the adhesive margin of thebinder-web is effected as the web travels toward the shear-blades bywhich the webs are severed into wrappers through the medium of a rotarymoistening-disk 61, Fig. 2, which is supplied with moistening liquidfrom a tank 62, Fig. 2, by disks 63 and 64, the latter dipping in thewater in the tank and supplying the liquid to the disk 63, which in turnsupplies the moistening-disk 61. The disk 61 projects up through thetable 19, as best seen in Fig. 17, and the adhesive margin of thebinder-web bears against the disk as the web is drawn or pulledlongitudinally by the nippers. The disks 61, 63, and 64 are mounted onshafts having pinions 65, 66, and 67 at one end, which engage each otherand are positively driven by a pinion 68, meshing with the pinion 67 anddriven by a gear-wheel 69, the latter'being rotated, as will hereinafterappear.

After the nippers have drawn the webs longitudinally in front of themagazine and the wrapper has been severed therefrom by the shear-bladesof the cutter and until the nippers again advance and seize the webs thelatter should be held or pressed down in a fixed position upon thesupporting-table 19 for the purpose of maintaining their leading ends inaccurate position to be seized by the nippers. Thisis effected throughthe medium of a pressing-finger 70, Figs. 1, 2, 4, and 18, extendingover the webs and secured at its rear end to a longitudinal rock-shaft71, which at proper timed intervals is positively turned by meanshereinafter explained to raise and lower the finger in such manner thatwhen the finger is lowered it will press upon and hold the webs and whenit is raised it will release the webs and perinittheni to be movedlongitudinally by the nippers; and, further, the reel 20, carrying theroll of tinfoil and waxed paper, should be arrested in its rotation andheldsteady afterthe reel has turned sufficiently to supply the wrappingmaterial necessary for a wrapper, as otherwise the momentum of the wheelmight unwind an undue quantity of the tin-foil and waxed paper, whichwould sag down and be more or less in the way, and thereforeobjectionable. To arrest the reel at timed intervals for the purposeabove stated, I provide the rock-shaft 71 with a brake, which, as hereshown, is in the form of an arm 72. (Best seen in Fig. 18.) Thebrake-arm 72 and the pressing-finger move in unison with the rockshaft71, so that-when the brake-armis caused to press against one end of thereel carrying the tin-foil and waxed paper the pressingfinger 70 iscaused to press down upon the webs and firmly hold the same.

It is proper at this point to generally describe the folding devices,and therefore I will proceed to set forth their construction andoperation, but will later on explain the mechanical devices by which allthe folders are positively actuated. The folding-box is of the samedimensions, substantially, as the dimensions of the article which is tobe wrapped, and-this folding-box is composed of the fixed front wall 40,Fig. 6, the pivoted clamp-jaw 4:1, upwardly and downwardly swingingend-folder wings 7 3, and oscillatory lateral tuckers or side-anglefolders 74,10- cated at the four corners of the box or chamher. Thelateral tuckers or side-angle folders are approximately hemispherical inform or shape and have beveled portions 74, as best seen in Fig. 10. Thewall 40 and the clamp-jaw 4.1 serve to turn the opposite longitudinalside portions of a wrapper to the perpendicular position shown in Fig.30, when the article and the wrapper are reversed and pushed into thebox by the gripping and transferring jaws 29 and 30. The end-folderwings 73 serve to fold upwardly end portions of the wrapper after otherend portions have been folded downwardly and the tuckers or side anglefolders have tucked or folded in the angle portions 8, Fig. 33. Thelongitudinal side portions of the wrapper extending above the article,as shown in Fig. 30, are folded down and lapped one over the otherthrough the-medium of front and rear longitudinal folders, composed, ashere shown, of thin flattened slide-plates 75 and 76. When the articleand wrapper have been inserted into the folding box or chamber and asthe gripping-jaw 29 leaves the same the front longitudinal folder-plate75 moves rearward and folds down one longitudinal edge portion of thewrapper upon the article, and immediately following this the rearlongitudinal folderplate 76 moves forward and folds the otherlongitudinal side portion of the wrapper, which is provided with theprojecting adhesive margin 4, Figs. 29, 30, and 31, down upon the otherlongitudinal fold. As this occurs the front folder-plate 75 movesslightly forward, so that there is a space provided be tween theadjacent edges of the two longitudinal folder-plates, which space isapproximately coextensive with the adhesive margin of the binder part ofthe wrapper. It is now essential to first form the downfolds 7, Fig. 33,at the-end portions of the tin-foil and waxed-paper parts of thewrapper. To accomplish this, I provide an arm 77, Figs. 1, 2, 3,4, '7,and 12, constructed to swing in a perpendicular plane and supported atone end through the medium of a stud-shaft 78, rig idly mounted in afixed bearing 79. This arm is hollow to form cheek-pieces 77" and 77*,Figs. 7 and 12, and carries two folder and gripper wings 80 and 81,arranged a distance apart substantially coequal with the length of thearticle to be wrapped. The folder and gripper wings are pivoted uponsmall axles or shafts 82 and 83, Fig. 12, and they are opened and closedat timed intervals by the means hereinafter described. The arm 77 isprovided betweenthe folder and gripper wings 80 and 81 with a flexibleor soft pressin g-pad 84, so that when the arm is lowered by
